I graduated in Chemistry (Biochemistry and Molecular Biology) in 1982 from the Universitat Autònoma de Barcelona, where I also obtained my PhD (in 1990). My training was completed in several places, but mainly atthe California Institute of Technology (Pasadena, USA; 7 years) and at the Centro Nacional de Biotec nología (Madrid, Spain; 2 years). Before my ICREA appointment I was Associate Professor in the Faculty of Medicine at the University of Bergen (Norway). Currently I am an ICREA Research Professor at the Universitat de Barcelona, Departament de Genètica, a position that I hold since the year 2003. The area of my research is the Evolution of Developmental Mechanisms in marine animal systems, with a particular focus on the origin and diversification of the nervous systems. At the Universitat de Barcelona I was also the head of the "Genetics" Doctoral Program.
